Are there any technical reasons DNN web pages might not be picked up for indexing by top search engines (Google, Yahoo, MSN)? I'm concernced about problems other than the standard SEO content issues like page copy, meta tags, inbound links, etc. I appreciate any feedback on this topic. Thank you. S

Please disregard any information that you already know below...

There are a multitude of things that could be problems for SEO due to the extensible nature of DNN.  There are simply too many to answer.  What you really should do is sign-up for a service like the Google Webmaster Tools (I think Microsoft and Yahoo have similar products now).  Then be sure to submit your site map to Googe through the Site Settings page and the Google Webmaster Tools area.  Once your site has been completely crawled, the crawl stats will show you where you problem areas are.  Another helpful tool in this area is the Google Analytics service.  This will also help you optimize your content and meta data.
